HEATING mjvnnriLe-TING svsfrria.-

TQ it my concern:

` Be it hat I, PRESTON BELvImciti- "zcn of the United States, residing at Riclb p mond, int e 'county of Henrico and State of lv Virginia, have invented certain new and useful' improvements in Heating and 14Ventilat- Systems, of which the following is a specifieation. .The present invention appertains to means fiori heatin and ventilatin rooms, apartilnentgha s and like places'eing of especial advantage for heating school rooms and rel '-moving'vitiated air.

hejinvention consists of a drum encir- ,115,y cling intuye or heater of an type and adapted to receive fresh air at tiie lower end and g eonne the same to insure its 'uppery end of c' arge the warm air, into the room oriother place yto be heated and ventilated. A foul air pipe is provided and has connection at its np r end with the chimney or'other outlet n `is in communication with the lower portion of the room and with the ash pit of the yMVitOVe or heater, a damper being arranged to y `control the current of air through the foul pipe so that the vitiated air may have a heating, the

direct passage to the chimney or outlet or be ."deflected yand caused to enter the ash pit of 'the stove or heater to create a draft there- .im `through for supporting combustion.

For a full understanding of the invention "and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be hadto thefol'lowing description and accompanying drawings i e' the invention inaybe adapted to diierent forms and conditionsby changes in the structure and minor details `without departin i from the spirit oressfvntial features lthereo still the preferred embodiment is shown in 'the accompanying drawings, in which: Figure 1 is a sectional view, showing the. `Lap lica'tion of' the invention. Fig. 2 is a detai yiew of the lower end of the foul air pipe. Fig. 3 is a horizontal section ol' the drum immediately above the mat.

The stove or heater l may be pi" any type, make or design. A drum 2 preferably of sheet metal, as steel, is arranged to ei'icircle the stove or heater and is aeed therefrom to provide foifainplc ciren ation ofair hel tween the sidesiof the heater drum.

the drum being open to dis Patented June 80, 1908.

air is supplied to the lower end of the drum and passes upward through the space formed between the drum and heater and is warmed in itsv ascent by the heat radiated from the stove, the heated air being discharged into the roor'n through the upper end of the drum, which is open for this purpose. The drum in the referable arrangement is placed upon iioor of the-room, a artment or the like, a close fit being Qbtaiiie( to prevent any foul air entering tii'e drum. "Fresh air is sup )lied to the lower; end 'ofqthe drum throng an opening formedin'theiloor,,said opening being arranged directly below the stove I or heater.- A register is ittedto the opening so as tofregulateihc amount of fresh air to beA admittedfroin the outside according to existing conditions. In the event of the air directly below the iioor containing any iinnrities, a pipe 3 maybe provided to extend beneath the floor and open ont through a wall of the building or structure, so as to receive a supply of air from the outside. f The inner end of the pipe 3 connects with a box. 4, which is iitted in the opening of the lloor, the 'upper end of the box being provided with the register embodying the damper 5.

The foul air ipe 6 is' adapted to have connection with tie chimney 7 or other outlet for carrying oil the smoke from the stove or heater 1 and its low'er end extends close to the floor oi the room, apartment or the like in which the heater' is placed, so as to receive the -foul and vitinted air which accumulates in the lowi-u'most strata of the room. The lower end of the Ioul air pipe (i is lnred, as

shown most clearly in Fig. 2, to provide an extended mouth lor gatheringr in the foul or heavy air. A branch pipe S connects with the lower portion ol' the l'onl air pipe (i and inclines downwardly therefrom and connects with the ash pit il olE the stove or heater. ly having the branch pipe S inclined, as shown, ashes, cindcrs and the like are prevented from passing from the ash pit therethrough and into the pipe (i and dropping upon thc floor. A damper l0, pivoted or hinged at ll, is adapted to control the current ol' air either through the pipe 6 or the branch t4. A rod l2 connects with the damper and passes through an opening in a side ol' the pipe 6 and is notched or, toothed to make `ciigngeineiit n'ilh said pipe to hohl the damper in any adpxsted position. The damper when, rceased, closes by gravitative action. A recess 13 is formed neer the juncture of th branch 8 with the pipe 6 to receive the lower portion of the demper l so as not to obstruct the entrance to the pipe 6.A 5 -A pipe section 3A iitted to the smoke pipe opening leading into the chimney 7, is of larger diameter than the smoke pipe 15 or y the foul air pipe so as not to impair or check draft therethrough. The upper section oi the foul air pipe 6 is enlarged, as shown et 16, whereby provision is had for accommodating the air as' the same is expanded as it approeches the ipe section M, thereby preventin any c ecking or diminution in the l1t draft t erethrough. .f

lt is well knownthat the lower strat of nir ina room, apartment or the like, is'laden with im urities, and the present invention prvi es for carrying oil such vitiated air. '2c When the parts are assembled, substantially es shown and herein indicated, a draft is created throu h the foul air pipe 6, and by reason of the fatter opening into the room close to the floor thereoi, the heavy or vitiated air is drawn thereinrand passes u ward and out throu'h the chimney or ot er discharge. The 'vitieted air thus disposed oi' is replaced by the fresh air entering the lower portion of the drum 2, said air being held Within the- So heating zone of the stove l by the drum 2 and warmed rior to its discharge from the upper end ci tA e drum into the room. For su orting combustion, the lower end of t e amper 10 ma be drawn outward, thereby causing the io .air to enter the lower portion of the pipe and thence pass through the branch 8 into the ash' pit and up through the body of coals in the stove and creating a vdraft therethrough in the manner well under lo vstood. The damper 10 may be set either to directthe entire current through the stove or 'through the ioni air pi e, orr'partly through each, as mav be foon to give the y best resnlts, The esh eir entering the lower por` ll5 tion of the drum and rising 1s deflected outward by coming in contact with the bottom ci the stove or heater, and after spreading horizontally@ asses through the space sur,- rounding the eater and is confined by the 5o drnniZ. The drum may be of any construction to admit of access being had to the stove door for feeding hiel/thereto and tothe ash.

pit for removing the ash pan or ashes. As

shown, a door 17 is provided in the lower portion of the drum opposite the ash it to ad- .;nrit of access vbeing readily had to t e latter.

@it is of the utmost importance that the ash pit be entirely closed, except for the opening 1n communication with the branch pi e 8,

so therebypreventing any of the fresh air eing utilized tor supporting combustion. y

iThe register may be of any construction end arrangement.' it may be tted in the open end of the'box e, or it may he psi-rt of e senese niet. Thel` inet i8 is of sheet motel rein- 65 forced at its outer edge and having its middle portion perforated and surrounded on three sides by e guide to properly position e slide 19 and direct it in its movements, said slide controlling the air admitted through the 7o openings oi the perforated portion 30 oi the I niet. f i

Having thus described the invention, what is claimed as new is: y
